There are only 2 ways that can happen, fission or fusion. Fusion is when two atoms combine to become a larger atom (almost exclusively two hydrogen atoms becoming 1 helium atom). Fission is much more common and is present in all radioactive elements.
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
145/62 sm is the daughter element in the above equation.
Seems some mistake in printing the mass number of thorium. It has to be 227. No Th-225 is available as far as the tables have been analysed. When a alpha particle comes out then the atomic number of parent is reduced by 2 and its mass number will be reduced by 4. So in case of Th-227, it gets changed to Ra-223 after the emission of an alpha particle.
If a bromine atom underwent alpha decay, the result would be an arsenic atom with a mass number four lower than the original bromine atom. I did a little research on this, however, and it appears that there are no bromine isotopes that undergo alpha decay. I have provided a link to the interactive table of nuclides.
The alpha decay of americium-241 produce neptunium-237.

No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
Product of radioactive decay 42He is an alpha particle
In alpha decay, the atomic number decreases by 2, while the atomic mass number decreases by 4.

Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.

That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
